\VATEB HEATER.

Application filed July 16,

My invention relates to a water heater of the storage type employingautomatic mechanism for regulating the heat of the water, and it hasparticular reference to a unit assembly of a water heating element andan automatic gas control in connection with water heater.

The prime object of the invention is to provide a heater for automaticaly controlling the heating and storing the heated fluid in which themechanism for controlling the heat and the heating element constitute aself contained unit which may be quickly attached to and detached fromatank.

Storage heaters as now constructed comprise heating means andthermostatic controls interlocked in integral relation, wherebycorrection of any injury or damage to the heater must necessarily beattended by a complete dismantling of the units thereof at the hands ofan expert and at the expense of further damage to the heater because ofrusted pipes, pipe fittings and other appurtenances, the removal ofwhich can be effected only with difficulty, and with special tools.Ordinarily it is almost impossible to remove either unions or directjoint of ordinary storage tank heater on account of size,inaccessibility and rust.

This invention is directed to the elimination of this drawback and hasfor it further objects to provide a heater in which the heating means,and the automatic control for such heating means are a compact unit,which may be quickly connected to and separated from, a storage tank,without any saecial tools, without removing the heater, and withoutspecial skill; in which the'unit may be tested out independent of thestorage tank; in which one unit of heating means and regulator may bereadily substituted by another; in which gaskets, packing or washers maybe wholly dispensed with, and in which but one element is needed toattach the unit to and detach same from the storage tank.

A preferred form of the invention is i1- lustrated in the accompanyingdrawing, the

; figure in which is a'fragmentary sectional view. v

The tank for storage of water is shown at 1, and the parts appurtenantto an automatic water heater comprise the parts shown; to wit, heatingcell 2, a thermostatic unit 3, a gas or other heating fluid-controllingyalve' 4,11, burner 5, and water cirgulatmg 191136 e,

1225. Serial No. 44,089.

The heating cell or element 2, is disposed above the burner 5, andcomprises a hollow body of any desirable shape, having a passageway 7extending vertically through said body, the passageway providedpreferably by a tubular member 8, penetrating the cell and welded orotherwise secured to the top plate 2 and bottom plate 2" and sealing thehollow cell 2. i

A water circulatingpipe 6 communicates with the interior of the cell 2and conveys the water, passing through the pipe 3 contaming thethermostatic unit 3, into the cell 2 through said pipe 6. To the top ofthe cell 2 1s threadedly or otherwise secured a pipe section 10, havinga threaded end 11 arranged for engagement with supporting member 12, towhich is also arranged to be fastened by threaded engagement theaforenamed pipe 3 in which is disposed the thermostatic unit 3. Thispipe 3 passes through ilajhe pasageway provided by the tubular mem- Thebottom of the tank 1,'is provided with a reinforcing plate 13, centrallyof which is threadedly or otherwise engaged therewith one end of a stud1 1-, which extends through a smooth bore 12 in the supporting member12, and the other end of which stud 14 is arranged to be engaged by anut 15, which extends through the passageway 8 in said cell and isoperable against the underside of the I supporting member 12, for thepurpose appearing presently.

Between the supporting member 12 and plate 13 and upon seats 12 and 13respectively provided in said supporting member 12 and plate 13 areplaced compression rings 16 and 17, having a double taper, for thepurpose of forming a perfect joint between the plates 12 and 13 whichare held conjoined by the nut 15. The seats 12 and 13* in saidsupporting member 12 and plate 13, respectively, are inwardly extendedand tapered and co-operate with the tapered compression rings 16 and 17in sealing the connection of the supporting member 12, and itsappurtenant parts with the plate 13 in the bottom of the tank 1. i

As seen in the figure, thefpipe section 10 affords direct communicationbetween the heating cell 2 and the tank l,which receives the heatedwater from the cell 2., 1 v

Theassembly of the heating unit with its 110 complementary parts,preparatory to associating-it with the tank 1- of th is ade y threadingthe upstanding pipe section 10 attached to the cell 2, into thesupporting member 12, then inserting the thermostatic rod-containingpipe 3 through the tubular member 8 and threading said pipe into themember 12. The thermostatic rod 8 is passed through the compression ring17 and into the tank 1, simultaneously with the placement of pipe 3. Thepipe 6 is then connected to the water heating cell 2, by union 6 orother means. Both the pipes 3 and 6 are connected to a fitting 19 orordinary type for circulation of water.

The heating unit resembled, as described and comprising the partsreferred to, in cluding the gas supply valve 4t, then associated withthe tank 1 in manner :r'ollowing. The compression rings 16 and 17 areset in position with the bottom taper in the seats 12 of the member 12.The nut 1-3 is then operated on the stud 14 and thereby the supportingmember 12 is moved relatively to the. stationary plate 13 in the bottomof the tank 1. By this movement, the compression rings 16 and 17 areforced into their respective seats 12 and 13 in the plate 13 and therebya tight and positive joint effected. The gas connection is then made at20 and the heater is ready for use.

To disconnect the heating cell 2, and its connected parts, from the tank1, it is only necessary to uncouple the gas connection 20 and then toremove the nut 15 from the stud 14. It will be seen, therefore, that thesupporting plate or member 12 carries the entire heating, andheat-control unit and that by a single nut 15, the entire unit may beattached to and detached from a tank without special tools, withoutskill, and without undue cost and expense of time and labor.

What I claim is:

1. In a water heater, including a water heating means, a thermostaticregulator and appurtenances, and a tank, a plate in the bottom of saidtank having extended therefrom a stud and provided with watercirculating passages, a supporting member for said heating means.thermostatic regulator and appurtenances, having openings in line withthe passages in said plate, means between said. plate and member toconnect the passages therein, and means ingaging said stud to connectsaid member to said plate.
